iptables:如何删除postrouting规则?

我想删除下面的POSTROUTING规则,

[root@hostname ~]# service iptables status Table: nat Chain PREROUTING (policy ACCEPT) num target prot opt source destination Chain POSTROUTING (policy ACCEPT) num target prot opt source destination 1 MASQUERADE all -- 192.168.1.0/24 0.0.0.0/0 Chain OUTPUT (policy ACCEPT) num target prot opt source destination 

然后我键入下面,

 [root@hostname ~]# iptables -D POSTROUTING 1 iptables: No chain/target/match by that name 

有什么不对的吗?

尝试显式添加表名:

 iptables -t nat -D POSTROUTING 1
